Canada has agreed to cover all construction costs of the U.S. customs plaza, and with the deal removed the last political hurdle Wednesday for the planned $2.1-billion Detroit River bridge.

The Canadian government has agreed to pay the $250 million cost for the inspection plaza in Detroit under a deal agreed to by both countries.

It had been hoped the Obama administration and Washington would pay for construction of its own customs plaza, but that will not happen under the newly signed agreement.

Canada along with a private sector partner soon to be selected by the Windsor-Detroit Bridge Authority — which is overseeing the project’s completion — will now be paying the Detroit River International Crossing project’s full construction costs.

The public-private partnership is expected to recoup construction costs in the years ahead through tolls and other potential revenue generators such as duty-free goods and gas.
